Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor light emitting device, along with its manufacturing method, capable of reducing disturbance in lateral mode in a relatively simple process to improve top hat form of NFP.  <P>SOLUTION: An n-type semiconductor layer, an active layer 15, and a p-type semiconductor layer are laminated on a substrate 11, and a p-side electrode 21 is provided on the p-type semiconductor layer. The p-type semiconductor layer is provided with a current constriction part 19 that corresponds to a light emitting region 15A of the active layer 15. A current guide region 19A whose carrier concentration is higher than the p-type semiconductor layer is formed beside the current constriction part 19. The drive current supplied from a p-side electrode 21 is guided to the light emitting region 15A directly below the p-side electrode 21 along the current guide region 19A of low resistance. Thus, the disturbance in optical output distribution at the end of the light emitting region 15A is reduced and the top hat form of NFP is improved for an improved lateral mode characteristics.  <P>COPYRIGHT: (C)2004,JPO&NCIPI
